First Claim
1. A method for transmitting image data in real-time between mobile communication terminals in a mobile communication system, the mobile communication system including a host mobile communication terminal, at least one client mobile communication terminal, an SMS server providing an SMS service to the mobile communication terminals, and a Packet Data Serving Node (PDSN) assigning Internet Protocol (IP) addresses through a Point-To-Point (P2P) protocol connection with the mobile communication terminals, the method comprising the steps of:
- when an IP address is received from the PDSN for an application of transmitting image data in real-time, transmitting by the host mobile communication terminal an invite message including the IP address to the client mobile communication terminal via the SMS server;
after receiving the invite message, receiving by the client mobile communication terminal an IP address from the PDSN, and transmitting a register message including the IP address to the host mobile communication terminal via the PDSN;
updating by the host mobile communication terminal a buddy list for communication partners based on the register message, and transmitting the updated buddy list to the client mobile communication terminal via the PDSN; and
exchanging by the host and the client mobile communication terminals the image data in real-time with each other based on the updated buddy list.
